El Prieto Cantina y Restaurant in Chula Vista serves birria and Baja-style mariscos from a covered patio complex at 3120 Main Street, an offshoot of the Mariscos y Birrieria El Prieto operation that has anchored the same block for over 25 years. The cantina format adds cocktails, micheladas, and a full bar program to the original food-truck menu, a sit-down craft-beverage approach to Chula Vista Mexican food that connects to the wider South Bay brewing scene anchored by 3 Punk Ales Brewing Co. Birria occupies the center of the menu — consomé served tableside as a complimentary starter, with quesabirria tacos, birria burritos, and birria fries built from the same slow-braised beef. Seafood plates run a parallel track through aguachile verde, shrimp cocktails, and whole fried mojarra, positioning the kitchen within Chula Vista's broader mariscos tradition alongside vendors such as T & M Seafood. The Don Vargas platter layers birria-braised beef over a flour tortilla with melted Oaxacan cheese and a 12-ounce side of consomé for dipping.
